Re: recent HP 35 "Red Dot" on Ebay Message #5 Posted by aj04062 on 26 Feb 2012, 2:56 p.m., in response to message #4 by D. Taylor
What is the date?
1211 and 1219?
I have an early, non red-dot SN 1143A 34416 with the same board layout and other PCA markings except instead of 1211 I have 05-72
This has the bug, but I also have what seems like a keyboard problem.
1/X acts like +, X<>Y seems to drop the last digit and makes the number negative (weird), R(down arrow) acts like CHS, STO acts like EEX, RCL acts like CLX.
Bad ROM or keyboard traces? I've been over it a couple of times and haven't seen anything..
